murr mm mmsenm, or nssamon-rna-nmm, Grimm. eommnsme Locorro'rrvn conducted from the, locomotive to the tender and the exhaust-steam back to the locomotive into the condenser. Ifthe auxiliary engine is arran on the locomotive andthe condenser on t e tender, the exhaust-steam of the auxiliary en e must'be conducted to the tender. In bot cases, it, is necessary to u e between the locomotive and tender fierible pipe-couplings which may be either hose or pipe connections iwith ball joints and when a state of vacuum exists in these connections they are kept air-tight with difliculty. Therefore, as soon; as a partial 2o vacuum arises in the exhaust eondmt and consequently in the flexible .pi connections .by a direct connection with ge condenser, the dan er exists of air sucked into the con ensr whereb the iency of the entire machine-plant is impaired. This drawback is obviated ,aceo to the invention by constru the a ary engines as reaction "engines or example as reaction. turbines) so that e flexible pipe coupling between the locomotive and tender, in-which a pressure above atmospheric will now prevail, is no 10 r connected directly to the condenser. Be ore entering-the condenser, the exhaust-steam may then still be utilized for doing work in a feed water like.

Fig. 2 a section along the line 2--2 of e live steam coming from the locomotive boiler flows through a pipe a'(Fig.' 1), a flexible pi b and a pipe 0 to a reaction turbine d, rivin the same. The turbine actuates a blower through the intermediary of a gearin e (Fig. 2-). discharged by the turbine 11 ata pressure slightly above atmospheric pressure returns through a pipe 9 and. a flexible pipe h to the ocomotive. -With the embodiment shown, the exhaust-steam is then caused to as flow through a feed water heater n and from ,same though a controlling valve i and 'a pipe p into the condenserk k. The con trolling valve 11 is regulated so as to hold the e austPBteam conduit under a certain to pressure as soon as the reaction turbine d is working. Instead of utilizing the exhaust-steam -for heating the feed water, it
